Key design elements and achievements
Maison Air et Lumière complies with the Active House principles, integrating energy, indoor comfort and the environment in the building design.
The home’s energy concept is based on optimal use of renewable resources (solar energy, natural light and fresh air) to minimize the need for air conditioning in summer, reduce heating in winter, and reduce artificial lighting use.
Insulation for heat consistency
A concrete base keeps the home insulated from below, while a low-temperature, under-floor heating system further improves indoor heat consistency. Despite the interplay of roof structures, the wood-frame building is compact and well insulated. To further ensure a stable and comfortable interior temperature, the interior walls are lined with terracotta tiles. The insulation efficiency, combined with the internal heat recovery and solar gains through the windows, reduce heating demands to a minimum.
Solar-powered heat, hot water and electricity
Heating and hot water are provided by a heat pump connected to VELUX thermal solar panels and photovoltaic solar cells installed on the steep, south-facing roof, which serves as a 5th façade. The home’s low-energy electric lighting, appliances and multimedia equipment are powered by the 35 m² of photovoltaic cells integrated in the roof. To further reduce electricity consumption, the home has an active façade with sensors that respond to changes in the outside temperature.
Intelligent ventilation and temperature control
The home’s hybrid natural/mechanical ventilation system adjusts according to the temperature and weather conditions. This means that despite the region’s warm summers, Maison Air et Lumière does not require air conditioning.
The VELUX Group designed the home with an eye on providing plentiful natural light. Maison Air et Lumière’s unusually high 1:3 window-to-floor ratio not only enhances the residents’ physical and psychological health and well-being and visually enlarges the interior spaces, but also saves energy by reducing artificial light use.
Flexible, thoughtful design
Maison Air et Lumière’s architecture is adapted harmoniously to its site and revolves around natural light and ventilation. Carefully positioned façade and roof windows bring in fresh air and sunlight from all directions to create an ideal environment and bathe the interior with a balanced, natural glow. Furthermore, the home’s unique and flexible design concept enables various compositions – whether the house is small or large, in town or in the countryside. The design allows the principles of comfortable living, energy efficiency and environmental quality to easily be applied in different contexts.
